I’m the keymaster but its affecting everyone. And it’s your traditional HTML, nothing fancy. A few span codes, but nothing is rendering at all.

In fact, and probably an even bigger problem: I just posted to the site from the VISUAL tab, and the resulting post was pure code! This has only started happening since switching to 2.3.1, and I’m also using your new plugin.

Sounds like you have a javascript error in your theme causing issues. Also, as a keymaster you’re allowed unfiltered HTML, but your regular users have limited access to HTML tags and attributes to prevent them from breaking the layout of your site.

What comes in bbPress 2.3.1 is exactly what we’re running here on bbpress.org.
